This document defines the procedure executed by a Member of a distributed inter-process communication (IPC) facility (DIF) or distributed application facility (DAF) to initialize a new Member as a fully functioning Member. This document defines the procedure for a new Member to enrol when the new Member was recently a Member of the DIF or DAF. This document is defined for use with DIFs, but it can be used equally well by a DAF that wants to assign synonyms with a scope limited to the DAF.
